I was trying to open the MySQL Database from the XAMPP (8.2.12) that I just installed on fresh Ubuntu 24.04.1 system. While the Apache Web Server and ProFTPD is running, MySQL refuses to start:

XAMPP Panel Error Status

Here's the complete error log:

I've tried numerous proposed solutions like this one, but none of them appears to be working.
